type of candy bar was eaten, if any.
What type of evidence most increases our confidence in experimental results? - 🧠
ANSWER ✔✔c) Three different scientists do three different studies, all with the
same result.
During an experiment to determine if people with more symmetrical body features
have a lower incidence of disease, a researcher first measures the length of several
bones in the subject's hands and arms. The device used to measure length does not
display a readout of the measurement taken. Instead, a wire connects the measuring
device to a computer that records the data. The computer monitor is kept out of
sight of the subject and the researcher. Why is such an elaborate device used? - 🧠
ANSWER ✔✔so that the measurements are not biased by the researcher
